Description
The
PPE
350Z
long
tube
headers
are
designed
for
maximum
power
and
midrange.
Testing
on
a
2006
350Z
showed
an
increase
in
top
end
power
and
midrange
torque
over
shorty
headers
and
testpipes.
JetHot
ceramic
coatings
come
standard
and
add
good
looks
along
with
thermal
barrior
properties
that
increase
power
and
lower
engine
bay
temps.
They
are
also
a
great
protection
against
corrosion.

Collector
Option:
Formed
Collector
w/
Spike
or
Parallel
Merge
Collector,
2.5"
Outlet
The
parallel
merge
collector
flows
a
little
smoother
and
will
give
you
a
little
more
scavenging.
Depending
on
what
your
goals
are
on
your
car,
it
may
be
worth
the
extra
money.
If
you
are
building
a
high-rpm
Naturally
Aspirated
motor
and
trying
for
every
last
bit
of
power,
the
parallel
merge
collector
will
give
you
the
most
power
gains.
If
you
are
building
a
street
car
with
just
bolt
on
modification,
the
formed
collector
with
spike
would
be
good
enough.
If
you
are
building
a
supercharged
car,
the
standard
formed
collector
with
spike
is
good
enough
as
the
exhaust
is
pressurized
and
scavenging
doesn't
make
a
big
difference.

Customer Questions
Question:
When purchasing the PPE Long Tube Race Headers, are new gaskets required for the exhaust manifold?
- Zayn Haniff
Answer:
Hey Zayn, you can generally re-use the stock gaskets, since they're steel
Question:
What is the difference between the formed merge collector with spike and the parallel merge collector? Also which is better for power?
- Zayn
Answer:
Hey Zayn, the formed merge collector is basically a pre-made collector that's welded in, and then the spike in the center is added to help the three channels merge smoothly. It's a simple design, but not ideal for performance. With the parallel merge collector, the runners are hand cut and welded to form a gradual, smooth merger into one. It's better for performance, but takes more work, hence the higher price.
